Battle of Porta Flaminia

The Battle of Porta Flaminia (December 1503) was a battle of the Italian War of 1499-1504 that was fought between the army of the Papal States and Cesare Borgia's Borgia soldiers at the Porta Flaminia in Rome. Borgia held his position at the gate with the mistaken belief that Micheletto Corella's army would arrive to help him with retaking Rome; instead, his last followers were killed or captured, and he was arrested by Fabio Orsini for murder, betrayal, and incest. The battle put an end to Borgia rule in Rome, which was now ruled by Pope Julius II.

History
Following the death of Pope Alexander VI in August 1503, many in Rome questioned whether they should still support the weakened House of Borgia. From 1500 to 1503, Ezio Auditore da Firenze and the Roman Assassins' Guild weakened Borgia control over Rome by assassinating Cesare Borgia's lieutenants and by destroying the Borgia towers overseeing the city. Borgia's army in Rome was destroyed by Auditore himself, as Auditore used the Apple of Eden to slay his forces in front of St. Peter's Basilica. Borgia later headed to a meeting with Cardinal Georges d'Amboise and sevearl other cardinals at the Colosseum, where he was informed that they had elected Cardinal Giuliano Della Rovere, an enemy of the family, to power. Borgia's guards there were also dispatched by Auditore, who wielded the power of the ancient artifact to kill many of them; unfortunately, Ezio lost several of his apprentices during the battle.

In December 1503, Auditore was informed by Bartolomeo d'Alviano that Cesare Borgia was rallying his best soldiers in front of the main gate into Rome, the Porta Flaminia. Auditore gathered the other members of the Assassins' Guild and faced the Borgia forces together. Borgia warned Auditore that Micheletto Corella's army was going to arrive, and that all of the Assassins would be slain. The Assassins succeeded in taking down Borgia's men in a battle at the gates, with Auditore again wielding the power of the Apple. After all of the guards were slain, a troop of soldiers began to approach the gate. Borgia claimed that Corella's troops were massing behind him and preparing to take back Rome, but Auditore informed him that Rome was no longer his; the troops turned out to be led by Fabio Orsini, who commanded them in the name of the newly-ascended Pope Julius II. Borgia was arrested for murder, betrayal, and incest, and he was dragged away in chains. Rome was now fully liberated from Borgia rule, and Cesare Borgia was arrested and taken away.
